Rainbow

A rainbow is a meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. It takes the form of a multicoloured arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the sun.

Rainbows can be full circles; however, the average observer sees only an arc formed by illuminated droplets above the ground, and centred on a line from the sun to the observer's eye.

In a primary rainbow, the arc shows red on the outer part and violet on the inner side. This rainbow is caused by light being refracted when entering a droplet of water, then reflected inside on the back of the droplet and refracted again when leaving it.

In a double rainbow, a second arc is seen outside the primary arc, and has the order of its colours reversed, with red on the inner side of the arc.

Overview

A rainbow is not located at a specific distance from the observer, but comes from an optical illusion caused by any water droplets viewed from a certain angle relative to a light source. Thus, a rainbow is not an object and cannot be physically approached. Indeed, it is impossible for an observer to see a rainbow from water droplets at any angle other than the customary one of 42 degrees from the direction opposite the light source. Even if an observer sees another observer who seems "under" or "at the end of" a rainbow, the second observer will see a different rainbow—farther off—at the same angle as seen by the first observer.

Short 330

The Short 330 (also SD3-30) is a small transport aircraft produced by Short Brothers. It seats up to 30 people and was relatively inexpensive and had low maintenance costs at the time of its introduction in 1976. The 330 was based on the SC.7 Skyvan.

Development

The Short 330 was developed by Short Brothers of Belfast from Short's earlier Short Skyvan STOL utility transport. The 330 had a longer wingspan and fuselage than the Skyvan, while retaining the Skyvan's square-shaped fuselage cross section, allowing it to carry up to 30 passengers while retaining good short field characteristics. The first prototype of the 330 flew on 22 August 1974.

The Short 330 is unusual in having all of its fuel contained in tanks located directly above the ceiling of the passenger cabin. There are two separate cockpit doors for pilot and co-pilot for access from inside the cabin.

While Short concentrated on producing airliners, the design also spawned two freight versions. The first of these, the Short 330-UTT (standing for Utility Tactical Transport), was a military transport version fitted with a strengthened cabin floor and paratroop doors, which was sold in small numbers, primarily to Thailand, which purchased four. The Short Sherpa was a freighter fitted with a full-width rear cargo door/ramp. This version first flew on 23 December 1982, with the first order, for 18 aircraft, being placed by the United States Air Force (USAF) in March 1983, for the European Distribution System Aircraft (EDSA) role, to fly spare parts between USAF bases within Europe.

Short Type 827

The Short Type 827 was a 1910s British two-seat reconnaissance floatplane. It was also known as the Short Admiralty Type 827.

Design and development

The Short Type 827 was a two-bay biplane with unswept equal span wings, a slightly smaller development of the Short Type 166. It had a box section fuselage mounted on the lower wing. It had twin floats under the forward fuselage, plus small floats fitted at the wingtips and tail. It was powered by a nose-mounted 155 hp (116 kW) Sunbeam Nubian engine, with a two-bladed tractor propeller. The crew of two sat in open cockpits in tandem.

The aircraft was built by Short Brothers (36 aircraft,) and also produced by different contractors around the United Kingdom, i.e. Brush Electrical (20), Parnall (20), Fairey (12) and Sunbeam (20).

The Short Type 830 was a variant powered by a 135 hp (101 kW) Salmson water-cooled radial engine.
